Redroot pigweed interference with lettuce crop [PDF]
Planta Daninha, 2020 Background: Lettuce-production areas in Brazil are frequently infested by pigweed plants, which can interfere with production by competing for resources or releasing allelopathic compounds in the environment. Objective: The present study evaluated the

Evaluation of techniques to break seed dormancy in Redroot pigweed (<i>Amaranthus retroflexus</i>). [PDF]
Food Sci Nutr, 2023 AbstractBy identifying the factors that initiate seed dormancy release, we can reliably predict whether a seed will remain dormant within or exit the seed bank and become a seedling. With regard to annual weed species, assessing which factors efficiently break seed dormancy is critical for estimating the number of weed seeds that will develop into ...
